JAMES RICK, OF READING, PENNSYLVANIA.

CASTER.

SPECIFICATION forming: part of Letters Patent No. 247,518, datedSeptember 27, 1881.

Application filed December 21, 1880.

To all whom it may concern:

Be it known that I, JAMES RICK, of the city of Reading, county of Berks,State of Pennsylvania, have invented a new and useful Improvement inFurniture-Casters, of which the following is a specification.

This improvement is applicable to all furniture-casters having thehorn-plate free to revolve upon the pintle, and is intended to givestill greater freedom and certainty to the action of the caster whileshifting its position upon the floor.

Referring to the drawings herewith ,'in which similar letters designatesimilar parts, Figure 1 is a sectional elevation of a caster showing myimprovement. Fig. 2 is a detail view of the pintle and washer.

A represents the socket-plate, which is of the usual form, and may beeither plain or threaded upon its exterior cone-surface. In the formercase the flange a would be a plain circular disk, and in the latter caseit would have portions of its periphery cut away or made of a polygonalform.

B is the pintle, passing through the hornplate D, and then slightlyreduced in diameter, as at B, for a purpose hereinafter disclosed. Aspace sufficient to prevent binding is left between the head I) and thewasher O. This latter rests upon the shoulder 11*, formed by the reduceddiameter of the pintleB,andis forced down upon the shoulder by machineryadapted for the purpose. D is the horn plate, carrying the wheelE uponthe axis 0. bis the top head of the pintle.

(N0 model.)

The drawings are sufficiently explicit for the information of experts inconstructing casters which require in their manufacture care only thatboth socket and horn-plate shall be free not looseon the pintle, andthat the latter shall not bind the horn-plate between the washer O andhead I), or the socketA between the washer G and head I).

This improvement gives a much freer movement to a furniture-caster thanis attainable with the ordinary construction of the same.

I am aware that it is not new for washers to be placed on the pintle ofacaster between the horn-plate and socket, nor for the horn-plate torevolve upon a pintle fixed or cast within the socket, nor for ahorn-plate with fixed pintle to revolve free in the socket, and I do notbroadly lay claim to either of these modes of operating as uncombined.

YVhat I do claim, and for which I desire to secure Letters Patent of theUnited States, is as follows, to wit:

In afurniture or other caster, a loose pintle, B B, headed at both endsand having shoulder b upon which rests a washer, O, in combination withhorn-plate D and socket A, the horn-plate and pintle being adapted torotate independently of each other, substantially as described.

JAMES RICK.
